Rancho RS5000X 4″ Front Lift Shocks for 1988-1999 GMC C1500 2WD

Part Number: RS55128

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted GMC C1500 trucks. Engineered for 4-inch front lift applications, these shocks utilize a unique Progressive Engagement Valving system to manage harsh impacts and reduce body roll. The gas-pressurized twin-tube construction ensures maximum durability and a smooth street feel, making it the ideal solution for daily drivers that require consistent performance over varied road surfaces.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between low and high-speed damping to ensure smooth ride quality without bottoming out.
• Nitrogen Gas Pressurization: A 150 PSI gas charge provides a consistent response and minimizes aeration to ensure fade-free performance during extended use.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and dent resistance to ensure long-term reliability in rugged environments.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the oil seal remains free of debris and contaminants.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened to accommodate a GMC C1500 that has already been equipped with a 4-inch lift kit.

Are these sold as a pair?
Yes, this SKU (2xRS55128_n599) includes a pair (2) of front shocks to cover both sides of your vehicle.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable; if the outer body is dented by road debris, the inner working cylinder remains unaffected, ensuring the shock continues to function properly.
